The TC Louisiana Intrastate Pipeline (TCLI) is an intrastate natural gas pipeline system that originates in Gillis, Louisiana and extends to various downstream Louisiana delivery points in Jefferson Davis parish.

The map depicts where the pipeline transports natural gas from Texas, Oklahoma, and Louisiana to cities and towns in Wisconsin, Michigan, Illinois and Ohio. The two major legs of ANR Pipeline converge near Chicago. ANR also provides access to TransCanada’s extensive natural gas storage operations in Michigan.
